ELECTROCHEMICAL CELLS & ELECTRODES

An electrochemical cell is a device that produces an electric current from energy released by a spontaneous redox reaction. It has two conductive electrodes, called the anode and the cathode. The anode is defined as the electrode where oxidation occurs. The cathode is the electrode where reduction takes place. Electrodes can be made from any sufficiently conductive materials, such as metals, semiconductors, graphite, and even conductive polymers. In between these electrodes is the electrolyte, which contains ions that can freely move.
